"We ended our transformational 2025 with a strong fourth quarter that underscored IBTROZI’s rapid adoption, and we believe our medicine is becoming the new standard of care for people living with advanced ROS1+ NSCLC across treatment lines. In 2026, we look forward to further building upon our successful U.S. launch, and partnering closely with Eisai to bring IBTROZI to more patients around the globe," said David Hung, M.D., Founder, President, and Chief Executive Officer of Nuvation Bio. "We are also excited and eager to progress our promising pipeline, with safusidenib now being studied in the pivotal Phase 3 SIGMA trial across those living with high-risk and high-grade IDH1-mutant glioma where significant needs exist for these patients. Lastly, we continue to evaluate additional internal preclinical candidates and external business development opportunities in hopes of furthering our mission to tackle some of the toughest challenges in cancer treatment."
Fourth Quarter 2025 and Recent Corporate Highlights:
IBTROZI (taletrectinib), ROS1 inhibitor: Advanced ROS1+ NSCLC
In the fourth quarter of 2025, 216 new patients started treatment on IBTROZI for advanced ROS1-positive (ROS1+) non-small cell lung cancer (NSCLC), reflecting the high rate of adoption and confidence in IBTROZI among healthcare professionals and patients.
With 432 new patients started since launch in the second half of June 2025, the treatment adoption rate is approximately six times greater than that of prior recent ROS1 tyrosine kinase inhibitor (TKI) launches based on IQVIA data.
On January 11, 2026, the Company entered an exclusive license and collaboration agreement with Eisai Co., Ltd. to develop, register and commercialize taletrectinib for the treatment of ROS1+ NSCLC in Europe, the Middle East, North Africa, Russia, Turkey, Canada, Australia, New Zealand, Singapore, the Philippines, Indonesia, Thailand, Malaysia, Vietnam, and India.
In the fourth quarter of 2025, the Company received a $25 million milestone payment from Nippon Kayaku as a result of establishing the reimbursement price in Japan.
In October 2025, the Company presented clinical data from the pivotal TRUST-II study evaluating IBTROZI in patients previously treated with entrectinib, a brain-penetrant ROS1 therapy at the European Society of Medical Oncology (ESMO) (Free ESMO Whitepaper) Congress 2025.
IBTROZI demonstrated a confirmed overall response rate of 80% in 10 patients whose tumors progressed following treatment with entrectinib.
Safusidenib, mIDH1 inhibitor: IDH1-mutant glioma
In December 2025, the Company announced the publication of positive results from a Phase 2 study of safusidenib in patients with chemotherapy- and radiotherapy-naïve grade 2 IDH1-mutant gliomas. The findings were first published online on November 8, 2025, in Neuro-Oncology.
Safusidenib demonstrated durable responses, with an ORR of 44% and 88% of patients were progression-free at 24 months.
The findings supported favorable interactions with the U.S. Food and Drug Administration (FDA) and the now finalized protocol amendment making the SIGMA study (G203) a Phase 3, pivotal trial evaluating safusidenib maintenance treatment in high-risk and high-grade IDH1-mutant gliomas. The study now also includes an additional exploratory cohort in grade 3 oligodendroglioma.
In October 2025, the Company enrolled the first patient in the global SIGMA study (G203).
Fourth Quarter and Full Year 2025 Financial Results
As of December 31, 2025, Nuvation Bio had cash, cash equivalents, and marketable securities of $529.2 million.
Product Revenue, Net
To date, our only source of product revenue has been from the U.S. sales of IBTROZI. We began distributing IBTROZI to our U.S. customers in June 2025. Net product revenue from U.S. sales of IBTROZI was approximately $15.7 million and $24.7 million for the three and twelve months ended December 31, 2025, respectively.
Collaboration and License Agreements Revenue
For the three months ended December 31, 2025, collaboration and license agreements revenue was $26.2 million, compared to $5.7 million for the three months ended December 31, 2024. The increase is primarily due to a $25 million milestone payment from Nippon Kayaku as a result of establishment of the reimbursement price for IBTROZI in Japan in Q4, offset by a $4.5 million decrease in research and development service revenue under the collaboration agreement with Innovent. Taletrectinib was included in China’s National Reimbursement Drug List effective January 1, 2026.
For the twelve months ended December 31, 2025, collaboration and license agreements revenue was $38.2 million, compared to $7.9 million for 2024. The increase is primarily due to a $19.1 million increase in license revenue and a $6.3 million increase in research and development service revenue as a result of milestone payment from Nippon Kayaku for the establishment of the reimbursement price in Japan in December 2025, a $3.6 million increase in product supply revenue, and a $1.3 million increase in royalty revenue.
Research and Development Expenses
For the three months ended December 31, 2025, research and development expenses were $34.3 million, compared to $29.3 million for the three months ended December 31, 2024. The increase was due to an $11.4 million increase in third-party costs related to clinical studies, offset by a $2.4 million decrease in personnel-related costs because employee compensation and benefit costs directly related to commercial drug production were capitalized into inventory, as well as a $4.0 million decrease in regulatory milestone payments to Daiichi.
For the twelve months ended December 31, 2025, research and development expenses were $115.1 million, compared to $99.1 million for the twelve months ended December 31, 2024. The increase was primarily due to a $7.8 million increase in salaries and other benefits driven by the increase in headcount and stock-based compensation primarily related to one-time charge for the vesting of performance-based awards upon receiving U.S. FDA approval of IBTROZI, a $12.1 million increase in third-party costs related to clinical studies, and a $0.1 million increase in amortization of assembled workforce, offset by a $4.0 million decrease in regulatory milestone payments to Daiichi.
Acquired In-process Research and Development Expenses
On April 9, 2024, as a result of the acquisition of AnHeart Therapeutics Ltd., we recorded a $425.1 million charge representing an acquired in-process research and development asset with no alternative future use in acquired in-process research and development expenses.
Selling, General and Administrative Expenses
For the three months ended December 31, 2025, selling, general, and administrative expenses were $40.3 million, compared to $26.1 million for the three months ended December 31, 2024. The increase was due to a $7.3 million increase in personnel-related costs as a result of the increase in headcount, a $5.9 million increase in sales and marketing expenses, a $2.1 million increase in legal fees, offset by a $0.4 million decrease in professional fees, and a $0.7 million decrease in foreign currency impact.
For the twelve months ended December 31, 2025, selling, general, and administrative expenses were $151.6 million, compared to $69.2 million for the twelve months ended December 31, 2024. The increase was due to a $39.4 million increase in personnel-related costs as a result of the increase in headcount and stock-based compensation primarily related to one-time charge for the vesting of performance-based awards upon receiving U.S. FDA approval of IBTROZI, a $41.0 million increase in sales and marketing expenses, a $3.1 million increase in legal fees, a $0.1 million increase in professional fees and a $0.3 million increase in other expenses, offset by a $1.5 million decrease in foreign currency impact.
Net loss
For the three months ended December 31, 2025, Nuvation Bio reported a net loss of $36.6 million, or $(0.11) per share. The net loss for the comparable period in 2024 was $49.4 million, or $(0.15) per share.
For the twelve months ended December 31, 2025, Nuvation Bio reported a net loss of $204.6 million, or $(0.60) per share. The net loss for the comparable period in 2024 was $567.9 million, or $(2.11) per share.

About ROS1+ NSCLC
Each year, more than one million people globally are diagnosed with non-small cell lung cancer (NSCLC), the most common form of lung cancer. It is estimated that approximately 2% of patients with NSCLC have ROS1+ disease. About 35% of patients newly diagnosed with metastatic ROS1+ NSCLC have tumors that have spread to their brain. The brain is also the most common site of disease progression, with about 50% of previously treated patients developing central nervous system (CNS) metastases.
About IBTROZI
IBTROZI is an oral, potent, CNS-active, selective, next-generation ROS1 inhibitor therapy. On June 11, 2025, following Priority Review and Breakthrough Therapy designations for both TKI-naive and TKI-pretreated disease, the U.S. Food and Drug Administration (FDA) approved IBTROZI for the treatment of adult patients with locally advanced or metastatic ROS1+ NSCLC. Learn more at IBTROZI.com.
About the TRUST Clinical Program
The TRUST clinical program comprises three registrational studies evaluating the safety and efficacy of IBTROZI. TRUST-I (NCT04395677) and TRUST-II (NCT04919811) are Phase 2 single-arm studies evaluating IBTROZI for the treatment of adults with advanced ROS1+ NSCLC in China (N=173) and globally (N=189), respectively. The primary endpoint of both studies is confirmed objective response rate (cORR) as assessed by an independent review committee. TRUST-IV (NCT07154706) is a Phase 3 placebo-controlled study evaluating IBTROZI for the adjuvant treatment of adults with resected early-stage ROS1+ NSCLC. The study will enroll approximately 180 patients in the U.S., Canada, Europe, Japan and China. The primary endpoint is disease-free survival as determined by investigator, and the primary completion date is estimated to be in 2030. Nuvation Bio is also sponsoring TRUST-III (NCT06564324), a confirmatory randomized Phase 3 study evaluating IBTROZI versus crizotinib in 138 patients in China with advanced ROS1+ NSCLC who have not previously received ROS1 TKIs.
Indication
IBTROZI is indicated for the treatment of adult patients with locally advanced or metastatic ROS1+ non-small cell lung cancer (NSCLC).
IMPORTANT SAFETY INFORMATION FOR IBTROZI (taletrectinib)
WARNINGS AND PRECAUTIONS
Hepatotoxicity: Hepatotoxicity, including drug-induced liver injury and fatal adverse reactions, can occur. 88% of patients experienced increased AST, including 10% Grade 3/4. 85% of patients experienced increased ALT, including 13% Grade 3/4. Fatal liver events occurred in 0.6% of patients. Median time to first onset of AST or ALT elevation was 15 days (range: 3 days to 20.8 months).
Increased AST or ALT each led to dose interruption in 7% of patients and dose reduction in 5% and 9% of patients, respectively. Permanent discontinuation was caused by increased AST, ALT, or bilirubin each in 0.3% and by hepatotoxicity in 0.6% of patients.
Concurrent elevations in AST or ALT ≥3 times the ULN and total bilirubin ≥2 times the ULN, with normal alkaline phosphatase, occurred in 0.6% of patients.
Interstitial Lung Disease (ILD)/Pneumonitis: Severe, life-threatening, or fatal ILD or pneumonitis can occur. ILD/pneumonitis occurred in 2.3% of patients, including 1.1% Grade 3/4. One fatal ILD case occurred at the 400 mg daily dose. Median time to first onset of ILD/pneumonitis was 3.8 months (range: 12 days to 11.8 months).
ILD/pneumonitis led to dose interruption in 1.1% of patients, dose reduction in 0.6% of patients, and permanent discontinuation in 0.6% of patients.
QTc Interval Prolongation: QTc interval prolongation can occur, which can increase the risk for ventricular tachyarrhythmias (e.g., torsades de pointes) or sudden death. IBTROZI prolongs the QTc interval in a concentration-dependent manner.
In patients who received IBTROZI and underwent at least one post baseline ECG, QTcF increase of >60 msec compared to baseline and QTcF >500 msec occurred in 13% and 2.6% of patients, respectively. 3.4% of patients experienced Grade ≥3. Median time from first dose of IBTROZI to onset of ECG QT prolongation was 22 days (range: 1 day to 38.7 months). Dose interruption and dose reduction each occurred in 2.8% of patients.
Significant QTc interval prolongation may occur when IBTROZI is taken with food, strong and moderate CYP3A inhibitors, and/or drugs with a known potential to prolong QTc. Administer IBTROZI on an empty stomach. Avoid concomitant use with strong and moderate CYP3A inhibitors and/or drugs with a known potential to prolong QTc.
Hyperuricemia: Hyperuricemia can occur and was reported in 14% of patients, with 16% of these requiring urate-lowering medication without pre-existing gout or hyperuricemia. 0.3% of patients experienced Grade ≥3. Median time to first onset was 2.1 months (range: 7 days to 35.8 months). Dose interruption occurred in 0.3% of patients.
Myalgia with Creatine Phosphokinase (CPK) Elevation: Myalgia with or without CPK elevation can occur. Myalgia occurred in 10% of patients. Median time to first onset was 11 days (range: 2 days to 10 months).
Concurrent myalgia with increased CPK within a 7-day time period occurred in 0.9% of patients. Dose interruption occurred in 0.3% of patients with myalgia and concurrent CPK elevation.
Skeletal Fractures: IBTROZI can increase the risk of fractures. ROS1 inhibitors as a class have been associated with skeletal fractures. 3.4% of patients experienced fractures, including 1.4% Grade 3. Some fractures occurred in the setting of a fall or other predisposing factors. Median time to first onset of fracture was 10.7 months (range: 26 days to 29.1 months). Dose interruption occurred in 0.3% of patients.
Embryo-Fetal Toxicity: Based on literature, animal studies, and its mechanism of action, IBTROZI can cause fetal harm when administered to a pregnant woman.
ADVERSE REACTIONS
Among patients who received IBTROZI, the most frequently reported adverse reactions (≥20%) were diarrhea (64%), nausea (47%), vomiting (43%), dizziness (22%), rash (22%), constipation (21%), and fatigue (20%).
The most frequently reported Grade 3/4 laboratory abnormalities (≥5%) were increased ALT (13%), increased AST (10%), decreased neutrophils (5%), and increased creatine phosphokinase (5%).
DRUG INTERACTIONS
Strong and Moderate CYP3A Inhibitors/CYP3A Inducers and Drugs that Prolong the QTc Interval: Avoid concomitant use.
Gastric Acid Reducing Agents: Avoid concomitant use with PPIs and H2 receptor antagonists. If an acid-reducing agent cannot be avoided, administer locally acting antacids at least 2 hours before or 2 hours after taking IBTROZI.
OTHER CONSIDERATIONS
Pregnancy: Please see important information in Warnings and Precautions under Embryo-Fetal Toxicity.
Lactation: Advise women not to breastfeed during treatment and for 3 weeks after the last dose.
Effect on Fertility: Based on findings in animals, IBTROZI may impair fertility in males and females. The effects on animal fertility were reversible.
Pediatric Use: The safety and effectiveness of IBTROZI in pediatric patients has not been established.
Photosensitivity: IBTROZI can cause photosensitivity. Advise patients to minimize sun exposure and to use sun protection, including broad-spectrum sunscreen, during treatment and for at least 5 days after discontinuation.
Please see accompanying full Prescribing Information.
About IDH1-Mutant Glioma
Gliomas are the most common type of brain cancer in adults worldwide. In the U.S., nearly 2,400 people are diagnosed with IDH1-mutant gliomas each year. Most patients are diagnosed in their 30s and 40s. While patients with IDH1 mutations generally have longer survival times than those with wild-type IDH1, gliomas are not currently curable and prognosis worsens for those with high grade tumors.
About Safusidenib
Safusidenib is a novel, oral, potent, brain-penetrant, targeted inhibitor of mutant IDH1. In Phase 1 and 2 clinical studies, safusidenib was well-tolerated and demonstrated anti-tumor activity and high blood-brain barrier penetration.
